Change in sleepin pattern !!

Hi moms! My daughter who use to sleep well at night and rarely take long naps has suddenly been sleeping a lot. She sleeps late at night and almost the whole afternoon to evening . I tried to get her back on her schedule but didn't work. should I be worried ?

    I wouldn't be too worried but maybe talk to her pediatrician about it.
    Waking her up would cause a grumpy baby, i'm sure it'll work out, Growth spurts do throw it off, just try to keep a steady schedule and make it bright during the day and play time and dark towards nap and bedtime. I try to prepare for the nap times, like 15 minutes before it's near nap time I make it dim and play soft music, those cues help her to stay on schedule.
